摘要:
三塘湖盆地火山巖地層巖性、孔隙結構復雜,電阻率測井受背景電阻率影響大,測井定量評價難度很大。針對巖性識別、物性參數和飽和度定量計算三大難點,利用圖像處理技術提取火山巖結構特征,結合常規測井資料特征,采用支持向量機方法在多維空間中識別火山巖性;以混合骨架模型和復雜孔隙結構模型為基礎,評價儲層基質孔隙、裂縫孔隙和滲透率等物性參數;通過消除背景導電飽和度模型,消除火山巖背景電阻率的影響,并利用裂縫孔隙性地層電阻率模型確定不導電水飽和度,求取非均質的復雜孔隙結構火山巖地層含油飽和度,從而形成了一套完整的火山巖定量評價方法。
Abstract:
In Santanghu basin, it is difficult to quantitatively evaluate the volcanic reservoirs since lithology and porosity structure is complex and reservoir resistivity is impacted by background resistivity. For simplifying lithologic identification,physical property and saturation calculation, proposed is a set of quantitative evaluation methods: Volcanic rock structure feature is extracted from electricity images using imaging processing technology; Combining with normal logging data, lithology is identified with SVM(Support Vector Machine)method in multidimensional space; On the basis of the mixed matrix model and complicated porosity structure model, it can evaluate block porosity, fracture porosity and permeability, etc. The saturation equation of eliminating background electric conduction is used to calculate oil saturation of the heterogeneous volcanic reservoir with complicated porosity structure, and to eliminate influence of the background resistivity; and nonconduction water saturation is obtained from fracture porosity reservoir resistivity model.
